About 3, idk what’s going on with my system, but sometimes after a big yay update, the kde login fails (something about the plasma environment failing to boot or idk I have not debugged it correctly yet), then after a reboot systemd-boot fails to load it and the efi entry dissapears. I’m forced to arch-chroot and reinstall the bootctl. After doing so, sometimes I have to do it again and other times it logs correctly.
Again, not debugged it correctly but it’s not like I did any kind of weird change to any config, just installed some flatpaks, some steam games, and lutris for League, which in the end is basically wine, and a yay update provoking this behaviour is pretty bad.
